Load relaxation of cold-worked and stress-relieved Zircaloy-4 near 673 K

Load-relaxation data obtained for both cold-worked and stress-relieved Zircaloy-4 are presented. The stress-relaxation curves, plotted as the logarithm of the applied stress against time, are interpreted in terms of an anelastic plastic constitutive equation, whose plastic component involves jog-dra...
